Research output: Contribution to conferencePaper


We report on efficient, single-junction bifacial perovskite solar cells (PSCs) that simultaneously exhibit high front-side-illumination power conversion efficiency (PCE) (over 22 %) and high bifaciality (over 91%), which represents a significant advancement for single junction bifacial PSC development. The bifacial PSCs exhibit substantial performance boost under concurrent front and rear illumination conditions. The stabilized power output goes up to 25.3 mW/cm 2 under albedos of 0.2, which is comparable to the state-of-the-art monofacial single-junction PSCs. Our work demonstrates the value and potential of bifacial single junction PSCs as an attractive direction for future scientific study and commercialization.
